Why do siblings compete?
Sibling rivalry is considered a healthy sign that children are able to express their needs or wants. However, if one of the children who creates the competitive environment feels excluded, it is important for families to take precautions.
Sibling jealousy is the rivalry between children of the same sex and similar age, and it results from siblings competing with each other to gain the love and respect of their parents. A certain level of sibling rivalry is considered a healthy sign that each child is able to express their needs or wants among children growing up in the same family.
However, if one of the children feels "excluded", which causes competition, families may need to be more careful and take precautions according to the situation.
